If there’s one thing we could say about chest straps, it’s that when you want to record the results of a tight walk, you feel like you’re getting ready for a game of Laser Quest. With the MZ-Switch, you feel a lot less like a twonk.
The MyZone MZ-Switch doesn’t completely fix the problem with optical heart rate monitors, but it does help with placement issues so that the data is better and more accurate. Stick to the recommended setting and exercises, and it can give you a good idea of how hard you’re working.

The MyZone MZ-Switch is a heart rate monitor that you can wear in different places on your body to measure how hard you are working during almost any type of exercise. It’s good for people who can’t stand having to wear a chest strap monitor during all of their workouts. You can track your heart rate from the wrist, arm, or chest.

MyZone MZ-Switch review: Design

The MZ-3 is pretty eye-catching with its bright red band, but the clip-on heart rate-monitoring module looks a little cheap, possibly because it’s made entirely of plastic. Still, it’s very easy to wear because the strap is made of Elastan and is stretchy and smooth.
Even when you work out for a long time, you won’t even notice you’re wearing it. It also has a part on the band that can be changed so you can make it fit just right. The Bluetooth module stays turned off until it feels skin contact, which is a smart design choice that helps the battery last longer.
So, if you’re trying to connect it to an external device and can’t figure out why it’s not in the list of possible devices, it’s probably because you haven’t turned it on yet. Once it’s in place, it will beep to let you know it’s ready to go.
MyZone MZ-Switch review: Performance
The Myzone app makes you feel like you’re part of a small group. The more you use it, the more you want to use it, which is motivational. If you forget to use your MZ-Switch before a workout, it doesn’t seem worth it to keep going if you’re not getting points.
There are some things it can’t do, though. Myzone won’t map your run, so it won’t tell you your pace, distance, rhythm, or any of that nonsense. It will only tell you how many calories you burned and how hard your heart worked.
Myzone’s solution is to let other apps do the heavy lifting, so it works well with apps like Strava, MapMyRun, Apple Health, and Garmin Connect that fill in the holes. You can also use an Apple Watch with it, and it also works with Samsung’s Tizen and Wear OS.
MyZone MZ-Switch review: Fitness tracking and app
The Switch is made up of a box that contains the sensor technology and a single button to turn on and off tracking. When worn on the wrist, an LED light will let you know when tracking has started and what heart rate zone you are in.
There is a comfortable chest strap to clip the module into, as well as one-size-fits-all armbands and wrists with Velcro to keep it in place. You can easily purchase this watch from its officially website.
There are Bluetooth and ANT+ connections, so you can pair it with MyZone’s phone app or third-party apps, watches, and workout equipment that are compatible. We were able to connect it to a variety of things without any problems.
MyZone MZ-Switch review: Sensors and accuracy
When worn on your chest, the MZ-Switch uses a smart ECG monitor, so you can be sure that the results you get are very accurate, much more so than with a typical smartwatch or fitness tracker.
When worn on your arm or wrist, the device switches to an optical PPG sensor. This method isn’t quite as exact as ECG, but it does the job just fine. There’s also the PPG gauge, which is based on light like most heart rate monitors worn on the wrist or arm.
It doesn’t use both kinds of heart rate sensors at once. When it’s on your chest, it uses the ECG sensor, and when it’s on your wrist or arm, it uses the visual sensor. You don’t have to do anything to change them. It does what you want it to do based on where or how you wear it.
MyZone MZ-Switch review: Battery Life

MyZone’s companion app has gotten better over the years, but if you’re going to use it as your main place to look at your data, we’d suggest using a third-party app instead, unless you’re all about those Myzone Effort Points. (MEPs).
On the main home screen, you can see a stream of workouts, such as monthly and total MEPs. When you click on the small MyZone logo at the bottom of the screen, you’ll be taken to a place where you can see your body metrics, such as your resting heart rate and your highest heart rate.
You can also see your body fat percentage and basal metabolic rate if you have other MyZone gadgets. From this screen, you can also ask to join and keep track of your workouts.
MyZone MZ-Switch review: Price and availability
When it comes to using gadgets to make real changes to your health and fitness, it can be hard to know where to start. After all, if you’re not very tech-savvy but want to start keeping track of your workouts, all the extras that come with smartphones and fitness trackers might seem unnecessary.
If that’s the case, a heart rate monitor made just for that purpose might be the best way to go. The Myzone MZ-3 fitness belt was first sold in 2015, and it cost £129.99 at the time. But since then, the price of the chest strap has gone down a lot.
You can now buy it from the brand’s main website for £79.99/$110, which is a $50 discount. That gets you the clip-on monitor and the chest strap, which only comes in bright royal red.
